Description

Mounting system and an associated locking method

The invention relates to a fastening system with a first adapter, a second adapter and a third adapter, in particular for and connectable with a

electronic device.

Electronic devices, such as The Siemens SINAMICS S120 low-voltage converters often have tabs with bores on their housings which can be arranged, for example, on upper or lower sides of the housings, and are stored in device cabinets via these tabs.

The equipment cabinets also have holes.

Through these holes and screw connections, an electronic device is hung in a device cabinet and secured in it against unintentional movements.

Are no further fasteners or

Holding devices provided, this results in the disadvantage that the electronic device, for example, must be supported during an assembly process by a mechanic until the screw connections are tightened. In order to ensure accessibility with tools (eg screwdrivers, ie to be able to tighten and loosen screws), these tabs must be exposed, ie projecting over the housing of the electronic device, resulting in an increased space requirement in the equipment cabinet Device can be stored in the equipment cabinet, can not be placed directly adjacent to this, but it must be complied with distances.

DE 10 2014 005 708 A1 describes a modular

Fixing system for building facade panels, in which at least one hook-shaped connecting element is arranged on a mounting bracket, in which a

form-matching connection receptacle is hung on the back of a facade panel. Furthermore, DE 71 29 501 U is known. Therein, a holder for an electrical appliance is disclosed which a

Base plate, with which an insulating part is connected, has. Latches arranged on the electrical appliance are in recesses in the base plate or the insulating part

insertable. Hooks connected to the electrical appliance snap into locking springs of the insulating part. Due to the tabs, the recesses and the locking springs, the electrical device is locked in the holder.

The invention is therefore based on the object of specifying a comparison with the prior art improved fastening system.

According to the invention, this object is achieved with a

Fixing system of the type mentioned,

in which the first adapter has at least one first slot tab with a first groove and a second slot tab with a second groove, which are arranged at an angle, in which the second adapter has at least one first slot

Guide tab having a first guide pin and a second guide tab with a second guide pin, which are arranged at an angle,

wherein the third adapter at least a first

Has safety bolt and a second safety pin,

wherein in the assembled state of the first adapter to the second adapter, wherein the first adapter adjacent to the second adapter, the second adapter is slidably connected to the first adapter and connected to the second adapter, in particular electronic device of the at least first securing bolt and the second

Locking pin is held, the first guide pin in the first groove and the second guide pin are arranged in the second groove, and in which the at least first securing bolt, between the at least first slot tab and the at least first

Guiding tab arranged in a first recess, are arranged by the at least first notch tab and the at least first guide tab and the second securing bolt, between the second and second tab slot in a second recess in the second slot and the second guide tab can be locked.

As a result, the advantage is achieved that the particular electronic device via the first Nutenlasche, the second Nutenlasche, the first guide tab, the second

Guide tab, the first locking pin and the second locking pin in position and held, i.

secured against unintentional movements and the number of fasteners required (e.g.

Screw connections) can be reduced.

This will reduce the assembly and

Dismantling effort achieved.

If the particular electronic device through the first slot tab, the second Nutenlasche, the first

Guide tab, the second guide tab, the first

Locking bolt and the second locking pin held vertically in position, this remains in place even with dissolved fasteners in position and must not be supported during the entire duration of an assembly or disassembly operation by a fitter or a device. Furthermore, there are no laterally projecting

Mounting tabs on a housing (e.g., on its top, bottom, right, or left sides) of the particular electronic fastener device (e.g.

Screw connections) required, resulting in a

Reduction of the space required for the particular electronic device results in a cabinet, ie, for example, more devices per unit volume can be arranged. An advantageous embodiment is obtained if the first recess is arranged on the at least first guide tab and the second recess on the second guide tab, wherein the first recess has a width greater than or equal to the diameter of the at least first securing bolt and the second recess has a width greater or equal to the diameter of the second securing bolt.

By this measure, a latching of the first adapter and the second adapter is made possible in the third adapter.

It is favorable if the at least first slot tab, the second slot tab, the at least first guide tab and the second guide tab are hook-shaped.

By this measure, a threading of the first adapter and the second adapter is facilitated in the third adapter.

An advantageous solution is obtained if the first adapter has at least one first securing tab and the second adapter has at least one third securing tab, wherein the at least first securing tab and the at least third securing tab have receivers for a fastening means.

By this measure, a lock of the

Fixing system and its associated, in particular electronic device via fastening means (e.g.

Screws).

It is advantageous if the second adapter is releasably connected to the particular electronic device.

This measure enables rapid replacement (e.g., in the course of maintenance operations) of the fastening system and the electronic device.

An advantageous embodiment is obtained if lines of the particular electronic device are arranged in a region between the first adapter and the third adapter. By this measure, a protection of the lines before

Environmental influences, damage (such as by crushing, etc.) and a favorable utilization of an available

Space budget achieved.

An advantageous solution is achieved when the particular electronic device has a first profile and a second profile, wherein the first profile in a first rail, which is detachably connected to a second wall, and the second profile in a second rail, which releasably with a third wall is connected, is arranged.

This measure facilitates the insertion and removal of a particular electronic device into an equipment cabinet as well as its positioning in the equipment cabinet.

An advantageous embodiment is obtained when a lever is connected to the first adapter, which has a receptacle for a fastening means.

By this measure, a lock of the

Fixing system and connected to him, in particular electronic device via the fastening means (for example, a screw) allows.

Furthermore, due to the functionality of folding the lever, permanently overhanging parts on the first adapter are avoided, resulting in e.g. Transport damage (e.g., canceling the lever), etc. can be prevented.

An advantageous solution is obtained when the lever is executed in a signal color.

By this measure, a clear indication of the condition of the lever is achieved. Unlike one

folded state is in a deflected state of the lever, the color mark visible and indicates an operator to this state.

Its cheap, when the first adapter with the second adapter is inserted into the third adapter in a manner that

at the end of this process, the at least first grooved tab on the at least first securing bolt and the second

Sliding tab hangs on the second safety pin,

when the second adapter, the first guide pin in the first groove and the second guide pin in the second groove move in such a way that at the end of this

Moving operation of the at least first securing bolt is arranged at least between the at least first Nutenlasche and the at least first guide tab in the first recess and the second locking pin at least between the second Nutenlasche and the second guide tab in the second recess, and

if with a fastener the at least first

Securing tab is releasably connected to the third securing tab.

By this measure, the process of positioning the particular electronic device in a device cabinet is separated from the process of locking. This will be the

Benefits that e.g. Immediately after inserting the electronic device in the equipment cabinet this no longer needs to be held to the lock by means of

Locking means (e.g., screws).

Even after a release of the locking means the particular electronic device remains in its position and is secured against unintentional movements.
